Abstract
A climbing steps rail set includes a first molded plastic rail having a lower end configured to rest on a lower support surface, an upper end configured to be coupled to an elevated support structure, and a first plurality of apertures formed in the rail and configured to receive respective first ends of steps to be supported by the rail set. The rail set further includes a second molded plastic rail having a lower end configured to rest on the lower support surface, an upper end configured to be coupled to the elevated support structure, and a second plurality of apertures formed in the rail and configured to receive respective second ends of the steps to be supported by the rail set.

A climbing steps rail set comprising:
- a first molded plastic rail having a lower end configured to rest on a lower support surface, an upper end configured to be coupled to an elevated support structure, and a first plurality of apertures formed in the rail and configured to receive respective first ends of steps to be supported by the rail set;
- and
- a second molded plastic rail having a lower end configured to rest on the lower support surface, an upper end configured to be coupled to the elevated support structure, and a second plurality of apertures formed in the rail and configured to receive respective second ends of the steps to be supported by the rail set;
- wherein each of the rails includes an integrally-formed graspable handrail extending substantially the entire length of the rail from the lower end to the upper end;
- and
- wherein each of the rails includes a recessed pocket adjacent each of the plurality of apertures for facilitating the insertion of a fastener into a step received in the aperture.
A playstation comprising:
- an elevated support structure positioned above a lower support surface;
- and
- climbing steps coupled to the elevated support structure for allowing a user to climb from the lower support surface to the elevated support structure, the climbing steps including;
- a first molded plastic rail having a lower end configured to rest on the lower support surface, an upper end configured to be coupled to the elevated support structure, and a first plurality of apertures formed in the rail;
- a second molded plastic rail having a lower end configured to rest on the lower support surface, an upper end configured to be coupled to the elevated support structure, and a second plurality of apertures formed in the rail;
- and
- a plurality of steps positioned intermediate the first and second rails, each step including a first end received in a corresponding one of the first plurality of apertures, and a second end received in a corresponding one of the second plurality of apertures;
- wherein each of the rails includes an integrally-formed graspable handrail extending substantially the entire length of the rail from the lower end to the upper end;
- and
- wherein each of the rails receives a plurality of fasteners to secure each step in the respective aperture.
A playstation comprising:
- an elevated support structure positioned above a lower support surface;
- and
- climbing steps coupled to the elevated support structure for allowing a user to climb from the lower support surface to the elevated support structure, the climbing steps including;
- a first molded plastic rail having a lower end configured to rest on the lower support surface, an upper end configured to be coupled to the elevated support structure, and a first plurality of apertures formed in the rail;
- a second molded plastic rail having a lower end configured to rest on the lower support surface, an upper end configured to be coupled to the elevated support structure, and a second plurality of apertures formed in the rail;
- and
- a plurality of steps positioned intermediate the first and second rails, each step including a first end received in a corresponding one of the first plurality of apertures, and a second end received in a corresponding one of the second plurality of apertures;
- wherein each of the rails receives a plurality of fasteners to secure each step in the respective aperture.
A climbing steps rail set comprising:
- a first molded plastic rail having a lower end configured to rest on a lower support surface, an upper end configured to be coupled to an elevated support structure, and a first plurality of apertures formed in the rail and configured to receive respective first ends of steps to be supported by the rail set;
- and
- a second molded plastic rail having a lower end configured to rest on the lower support surface, an upper end configured to be coupled to the elevated support structure, and a second plurality of apertures formed in the rail and configured to receive respective second ends of the steps to be supported by the rail set;
- wherein the first and second rails each include an interlock member configured to orient the first and second rails with respect to one another for packaging and to substantially prevent relative movement between the rails.
A playstation comprising:
- an elevated support structure positioned above a lower support surface;
- and
- climbing steps coupled to the elevated support structure for allowing a user to climb from the lower support surface to the elevated support structure, the climbing steps including;
- a first molded plastic rail having a lower end configured to rest on the lower support surface, an upper end configured to be coupled to the elevated support structure, and a first plurality of apertures formed in the rail;
- a second molded plastic rail having a lower end configured to rest on the lower support surface, an upper end configured to be coupled to the elevated support structure, and a second plurality of apertures formed in the rail;
- and
- a plurality of steps positioned intermediate the first and second rails, each step including a first end received in a corresponding one of the first plurality of apertures, and a second end received in a corresponding one of the second plurality of apertures;
- wherein each of the rails has a body thickness along a substantial portion of the rail and a mounting portion at the upper end that is thinner than the body thickness;
- wherein a transition between the body thickness and the thinner mounting portion defines a shoulder configured to align the rail for mounting to the elevated support structure;
- and
- wherein the elevated support structure includes first and second generally vertical members, and wherein the shoulder of the first rail is generally aligned with an edge of the first generally vertical member and the shoulder of the second rail is generally aligned with an edge of the second generally vertical member.
